Android :: ExpandableListView Displays Expand/Collpase Icon Even If There Are No Children

Nov 18, 2010

I have a ragged hierarchy of parents and children. In that there are some parents that have 5 children...and some parents have 0 children.

The expandableListView displays the "Expand/Collpase" icon even if there are no children.

Question-Is there a way to hide the icon for only those Parents(rows) that have no children? I still want to show the row of the Parents with no children. And allow a user to click on them. But the "Expand/Collapse" icon is confusing.

Android :: Webview Anchor Link - Jump Link - Not Working

Jun 14, 2010

I have a WebView in my Android App that is loading an HTML string using the loadDataWithBaseURL() method. The problem is that local anchor links (<a href="#link">...) are not working correctly. When the link is clicked, it becomes highlighted, but does not scroll to the corresponding anchor.

This also does not work if I use the WebView's loadUrl() method to load a page that contains anchor links. However, if I load the same URL in the browser, the anchor links do work.

Is there any special handling required to get these to work for a WebView?

I am using API v4 (1.6).

There isn't much to the code, here are the relevant parts of some test code I've been working with:

Android :: Way To Expand VM Limit In Phone?

Nov 23, 2009

Is there a way to expand the VM limit in Android 2.0 on an actual device? Using java.lang.Runtime.maxMem() on a Droid reveals a limit of 24MB, and I've written some code that incrementally allocates memory until failure to verify that figure. You can set the VM size in the emulator, but I haven't yet found a way to do that for a connected phone. Is there some type of a properties file on the device itself that can be modified?

Android :: ScaleType Expand To Screen

Nov 21, 2010

I need to resize several images inside ImageView to screen size. Currently I use scaleType="centerInside", it works good for bigger images to scale them down to screen size but doesn't expand small images.

All other suggested options crop or deform image. Is there any way to expand images (keeping ratio) via XML or do I have to do it manually in code?

Android :: Eclipse ClassCastException When Trying To Expand XML Layout

Jan 16, 2010

I am new to java, eclipse, and android development, so I may be missing something simple although I have checked basic stuff like spelling several times.

Because there is no number picker control (such as that used in the date picker) in the public Android SDK, the conventional wisdom is to "clone and own" the control that exists in the Android source.

In an attempt to do that, I have copied the code for NumberPicker into my project and its dependency, NumberPickerButton. I have also copied the supporting resources.

The problem I am having is that when I try to include the NumberPicker in a layout, the rendered version of the layout within Eclipse does not work.

CODE:...............

Adding that tag causes the Layout view of the XML file to only show the following error.

ClassCastException: com.spencerandbrown.PatientTracker1.NumberPickerButton cannot be cast to com.spencerandbrown.PatientTracker1.NumberPickerButton

I have tried both the fully qualified name and the unqualified name and it makes no difference.

The strange thing is that the control works at run time, it just will not render in Eclipse.

Is there a solution for this issue? Am I just doing something wrong?

If necessary, I can include more code from my project to clarify.

If I reference the internal Android widget, it works fine in the Eclipse layout view, but it is clumsy to interact with that way and it might break in the future.

CODE:............

Here is the stack trace from Eclipse.

Samsung Fascinate :: Need To Expand Text Message Limits To 5K

Didnt see an existing thread on this; sorry if this is a repeat.By default the SF stores 200 texts per conversation and 20 multimedias per conversion. However, that value can in both cases be adjusted up to 5000. Might be excessive but here's how if you haven't already done it: Open Messaging App>Menu>Settings>Text Message Limit>Tap the number and put in 5000>Set and you're done. **If you put in a value greater than 5000 it still ends up as 5000; must be the limit** With 5000 thats gonna be some really long threads but oh well.

Android :: How To Expand ListView As List Item Populate?

Aug 23, 2010

Basically I am trying to recreate the default contact screen when you click on "+" button another row of Phone number added to the list. Right now I have an ImageView as the "+" button and a ListView to contain the list of phone numbers. The problem is that the ListView doesn't expand when I add more item into the list. I could build the same look with LinearLayout but how can I save all those numbers that way? Below is the layout of the item that will be inflate with custom Adapter:

<?xml version="1.0" encoding="utf-8"?> <TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="60px"
android:stretchColumns="1" android:background="#FFFFFFFF"
android:gravity="center_vertical"> <TableRow>
<Button android:id="@+id/type" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:text="Home" /> <RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:paddingRight="10dp" >
<EditText android:id="@+id/value" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" android:text="" android:hint="Name"
android:lines="1" android:textSize="10pt" android:typeface="sans"
android:textColor="#FF000000" android:gravity="left" /
</RelativeLayout> <ImageView android:id="@+id/del"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:paddingRight="14dp" android:src="@android:drawable/ic_delete" />
</TableRow> </TableLayout>

This is the ListView portion.
<ListView android:id="@+id/phoneList" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#FFFFFFFF"
android:scrollbars="none" />

HTC EVO 4G :: Text In Browser Will Auto Adjust When You Expand The Screen

Jun 7, 2010

I have spent the last two years with the Instinct. Now with a couple days on the Evo I would like to comment on a couple of big improvements. I liked the Instinct and it was flawless as a phone. The Evo with its large screen blows it away. Colors on videos and in photos on web browsers are way better. I am a webmaster for a site that is very photo intensive and my opinion is that the Evo colors are very accurate. This is no small thing as our customers need to see the products clearly if they are to make buying decisions. Text in the browser will auto adjust when you expand the screen and I could read articles without my reading glasses which I need for almost everything. These two things make the web actually usable on my phone now.

Android :: Expand Clickable Area Of An ImageView By Using Padding?

Nov 5, 2010

I have an ImageView, and I want it to be clickable. The image itself is only 32x32 pixels, but I want the clickable region to be larger so it's easier to hit. I was hoping I could set the layout margin values to increase the size of the imageview's clickable area:

<ImageView
layout_width="32dip"
layout_height="32dip"
layout_margin="20dip" />

That doesn't work, what I could do is just recreate the image resource to have a larger transparent region around it. That's a bit annoying because it's hard to tweak if I ever need to change the clickable region. It's not just a single png either, it's a statelistdrawable so I have to resize 3 different pngs if I ever need to tweak the clickable area.

Anything else I can do?

Not interested in installing a theme just for this, they are not my gig, so I will pass on that as an option - so if the answer is no then, no worries.

Android :: List View Elements In Dialogs Never Expand To Full Width

Mar 31, 2009

I am rendering a ListView inside a dialog. The ListView elements are very simple TextView objects. The problem: whatever I do, they never take the full width in the list view, which has the side effect that the list view selector only covers the actual text, not the whole list entry (i.o.w., if the text of the entry is much smaller than the width of the listview/dialog, then only a tiny portion of the list element is highlighted when focusing it).

Android :: ExpandableListView Won't Redraw

Jul 29, 2009

I have an expandable list view with a static array for the group data and an SQLite database for the child data. It is implemented with the BaseExpandableListAdapter and works great, except, when I edit the database to delete or add children to the list I do not see the changes onscreen. It looks like I can use the registerDataSetObserver method to notify the adapter and expandable list of a data change. What I have to do in the callback to make Android redraw the list after data changes is what I need to know. Can I do it? Documentation on this part of the SDK is a bit sparse and expandable list view example code is not a good match. Can anyone offer advice on how to use a DataSetObserver? It feels like I have to switch over to a Cursor type adapter.

Android :: ExpandableListView - Is Conditional Expansion Possible

Aug 12, 2010

I have an ExpandableListView bound to a SQLite database. To simplify things, lets assume the database contains two columns: title and body. In the ExpandableListView, there is a group for each title, and a childfor each corresponding body.

Now to make things more interesting, some of the rows in the SQLite database do not have a body (that is... they only have a title). As you can see, if there is no body, then there is no reason to expand the group... because the child will be empty (i.e. String body == "").

I'm searching for a way to catch a situation like this, and skip the group's expansion. I don't want a blank child to be expanded. To put it in psuedo code, I want something like this:

Android :: Implement An Activity That Uses ExpandableListView

Sep 3, 2010

Im trying to implement an activity that uses ExpandableListView and I have gotten so far but now I have found some strange behavior.

My activity is meant to record food intake as specified by the user. they have a choice of menus (breakfast, lunch and dinner - the outer group) which expand to show their contents.
when a user clicks on an inner menu item a dialog appears asking them for the qty. once they enter a qty and dismiss the dialog the text on the menu item changes to reflect the quantity of that item that has been consumed

The above image shows the list in a closed state.

Below is the list after I have opened the lunch menu and clicked on 'Potato Chips' and indicating a Quantity of 1. As you can see the 'Potato' itemtext has now been changed to reflect the Qty of 1.

The strange part happens now. if I click on 'Lunch' and close the list and then click on it again re-opening it, the 'Qty X 1' text has jumped to another item (Milk)

Each time I open and close the list it jumps back and forth between the two items. Also if I open up other items, such as breakfast, I find that they too have now gotten items with 'Qty X 1' even though I havent clicked them.

The bits of code that are relevant are as such:

The XML for a child element:

CODE:................

The code thats triggered on clicking a child element:

CODE:..................

The above code opens a dialog, accepts a value for quantity, appends the list element to reflect this, also saves to database and sets a textview with the selected item and quantity.
